Function: 1. Wind turbine controller: Our 400W wind turbine controller is perfectly optimized pod for wind turbines and offers flexible 12V 24V voltage adaptation. This unique feature provides the controller versatility and the ability to adapt it to different power requirements. 2. Protective: This controller controls the wind turbine to automatically power the battery. When the battery is peny, the wentylator is inhibited by the internal circuit control system. When the battery voltage drops to the recovery voltage, the wentylator resumes advertising the battery, thereby protecting the wentylator and the battery. 3. IP67 water resistance: Comprehensive IP67 waterproof level, not easy to wet conditions, more reliable. Even when placed in water, it can be used normally for a long time, greatly increasing stability and reliability. 4. Good heat dissipation: The wind turbine controller uses aluminum housing with good heat dissipation. Part of the rectifier circuit and driver brake adopts integrated modu design. 5. Safety: To automatically control the battery of the wind turbine generator, generator wind and prevent the battery from overcharging. Enjoy peace of mind knowing that your wind energy system is working safely and efficiently.
